Colorado River / Lake Mead 24

Colorado River 24 is made up of several separate sites. Most of the time when we visit a site along the river or lake, we can be fairly certain that the site is either a petroglyph site (well duh), a habitat, ceremonial site, or a place where a sentinel may have been posted to watch people traveling the river, but in this case I am not really sure what we were looking at.Some of what we found looks like a bunch of rocks, but when you look closely, you will see definite patterns in the rocks. Sometimes they are laid flat and sometimes they will be standing on end or vertical.
